What is Urea formaldehyde
Melamine is an organic compound that can be combined with formaldehyde for making melamine resin, which is well water, heat & arc resistant and bright. It can also be used in decorative laminates and wood adhesives, aminoplastics, adhesive agents, coatings and used as a paper reinforcing agent, textile auxiliaries,flame retardants, cement water-reducing agent and leather retaining agent etc.
Urea formaldehyde is an opaque thermoset resin produced by heating urea and formaldehyde in a solution of ammonia or pyridine. It is widely used as a molding material and component of adhesives and protective finishes. The fiberboard industry is a large consumer of this resin, where it is used as a binding agent. Despite its many positive attributes, it can release formaldehyde gas under certain conditions. These resins are available as viscous liquids or as spray dried powders that require the addition of water prior to use.
It has the following features: high strength, anti-scratch, anti-heat, no poison, good shining, bright color and no color changing issue with long term use.
